Answer:
Step-by-step explanation:
the sum of the interior angles of a triangle is 180°
so
9x + 3 + 11x - 21 + 5x - 2 = 180
25x = 180 - 3 + 21 + 2
25x = 200
x = 200 : 25
x = 8
----------------
E = 9 * 8 + 3 = 75°
D = 5 * 8 -2 = 38°
F = 11 * 8 - 21 = 67
-------------------------
check
75 + 37 + 67 = 180°
Answer: 0.65
Step-by-step explanation:
Let A denote that moviegoers were female and B denotes that moviegoers were under age 25.
As per given we have,
P(A)=0.56 P(B)=0.26 P(A∩B)=0.17
Using formula ,
Hence, the probability that a moviegoer is either female or under age 25 = 0.65

Answer:
participant bias
Step-by-step explanation:
Participant bias is sometimes called as subject bias. it is referred to as the tendency of a subject that forces them to act in an experiment. it is held because that they think researchers is looking up to them to act. it occurs only when the subject has detail knowledge about the study or project.
Participant bias is a subject initiative to know about the inner thought of the researcher so the subject acts according to what the researcher wants to hear.
